What is the formula unit mass of ZnCl2?

Answer:
The formula unit mass of ZnCl2 can be calculated by adding up the atomic masses of the individual elements in the compound. To do this, we need to know the atomic masses of zinc (Zn) and chlorine (Cl).

The atomic mass of Zn is 65.38 g/mol, while the atomic mass of Cl is 35.45 g/mol.

ZnCl2 consists of one zinc atom (Zn) and two chlorine atoms (Cl). Therefore, we multiply the atomic mass of Zn by 1 and the atomic mass of Cl by 2.

Calculation:
(1 * atomic mass of Zn) + (2 * atomic mass of Cl)
= (1 * 65.38 g/mol) + (2 * 35.45 g/mol)
= 65.38 g/mol + 70.90 g/mol
= 136.28 g/mol

Therefore, the formula unit mass of ZnCl2 is 136.28 g/mol.
